For this first season, all 10 teams are driving the Spark-Renault SRT_01E, a car built by Spark Racing Technology, in partnership with Renault, Dallara, McLaren, Williams, Hewland and Michelin. Maximum power is 200 kw (270 bhp), but during the race the cars run in “power-saving” mode, which limits the power to 150 kw. A quirky feature called FanBoost allows one driver elected by race fans to temporarily increase maximum power to 180 kw.

Maximum speed is 140 mph, and acceleration from 0-62 mph is 3 seconds (bye-bye, BMW i8 pace car!). The Williams battery pack carries a modest 28 kwh of energy (just a bit more than a LEAF), but there’s no range anxiety on the track – each driver has two cars, and they simply switch midway through the race.
